移民了可活得比現在更快樂?
不少朋友、客人，說想要移民多年，仍沒有真正去付諸實行。問他們原因，他們說是因為移民去一個新的地方，不知是否能適應。說到底就是不確定移民了可活得比現在更快樂。在2018 年，World Happiness Report 為移民在移民後的快樂指數做了一個統計。
Increasingly, with globalization, the people of the world are on the move; and most of these migrants are seeking a happier life. But do they achieve it?
移民快樂指數統計是基於整體民生狀況
是次統計是基於移民在移民國的整體民生狀況：收入、健康、壽命、社會支援、自由及人與人之間的信任及分享。
All the top countries tend to have high values for all six of the key variables that have been found to support well-being: income, healthy life expectancy, social support, freedom, trust and generosity.

移民快樂指數的三個因素：生活質素，正面感受，負面感受
表3.1 展示了評核移民快樂指數的三個因素：生活質素，正面感受，負面感受。報告比較了人移民與不移民的快樂指數。
The report compares the happiness of migrants to what their happiness would have been had they not migrated.
統計報告發現，移民後的快樂指數有所提升： 生活質素提升9%，正面感受包括 (1) enjoyment, (2) laughter, and (3) happiness 提升5%，負面感受包括 (1) worry, (2) sadness, and (3) anger 減少7% 。
By comparing migrants to matched potential migrants and stayers without migration plans, we estimate that migrants across the globe evaluate the quality of their lives on average 9% higher following migration. They also experience approximately 5% more positive affect （enjoyment, laughter, and happiness）and 7% less negative affect （worry, sadness, and anger）due to migration.
